The synthesis, antibacterial activity and oral absorption of 3-(1H-1, 2, 3, -trazol-4-yl)thiomethylthio-3-cephem-4-carboxylic acids with various C-7 side chains (2) are described. The (1H-1, 2, 3-triazol-4-yl)thiomethylthio C-3 side chain was found to be an effective substituent for good oral absorption of cephalosporins with some C-7 side chains.
介绍了具有不同 C-7 侧链 (2) 的 3-(1H-1,2,3,-三唑-4-基)硫代甲硫基-3-头孢-4-羧酸的合成、抗菌活性和口服吸收。研究发现,(1H-1, 2, 3-三唑-4-基)硫代甲硫基 C-3 侧链是具有某些 C-7 侧链的头孢菌素口服吸收良好的有效取代基。
